A new study published in the journal Cancer suggests that risk of meningioma, a potentially debilitating type of non-cancerous brain tumor, was associated with receiving frequent dental X-rays before X-ray dosages were lowered.
Researchers from the Yale University School of Public Health analyzed data from 1,433 patients who were diagnosed with the tumor as well as a control group of 1,350 individuals with similar characteristics who did not have the tumor. The study found that over a lifetime, individuals who developed meningioma were more than twice as likely as those in the control group to report having received "bitewing exams" (which use X-ray film held in place by a tab between the teeth) on a yearly or more frequent basis.
